| 中文摘要: |
| 在烤烟生长中后期 ,应用40%菌核净500倍液人为控制烟草赤星病发生程度 ,形成不同危害梯度 ,以研究烟草赤星病对产量产值的影响。经试验分析 ,建立数学模型。中上等烟产量损失率(Y1)与病情指数(X)的关系式:Y1=0.1516+1.2824X;产值损失率(Y2)与病情指数(X)的关系式:Y2=0.3239+0.9831X。 |
| 英文摘要: |
| Effects of tobacco spot disease on tobacco output and quality were studies throngh establishing a damage gradient controlled by 500×40% Junhejing WP during middle and later growth periods of tobacco. Based on the experimental data, two mathematical models were established, i.e. the relationship between disease index (X) and tobacco loss rate of output (Y1) was Y1=0.151 6+1.282 4X, and the relationship between disease index (X) and tobacco loss rate of quality (Y2) was Y2=0.323 9+0.983 1X. |
